Jacobi-Sohncke Type Mixed Modular Equations And Their Applications


In this paper, we establish Jacobi-Sohncke type several new mixed modular equations for composite degrees 1, 3, n and 3n. As an application, we establish the modular relations between the Ramanujan-Selberg continued fractions H(q),\ H(q^3),\ H(q^n) and H(q^{3n}) for n=2,3,4,5,7,9,11 and also we obtain congruence relations for color overpartitions of n with odd parts.
